AFAIK, the only difference between the two is grip angle.
On a personal note, I have a scoped stainless steel MKII with the
6-3/4" slabside barrel. It's a favorite plinker, and a great
varminter. Minute of ashtray out to 80 yards.
Just got Hogues, don't have to sweat scratching up the
wood grips anymore. My favorite 22LR.
